Definitions

  • the invention relates to hygienic tampons, more specifically to menstrual tampons.
  • Conventional hygienic tampons are made of synthetic materials, polymeric foam layer, cotton or rayon, that during production and bleaching emit dioxin, a health and environmentally hazardous pesticide ( Nicole, W., 2014. A Question for Women's Health: Chemicals in Feminine Lubricants, Environmental Health Perspect 122, A70-75, https://doi.org/10.1289/ehp.122-70 ). Often cellulose-based tampons may have an outer layer of plastic or a plastic-coated string.
  • TSS toxic shock syndrome
  • vaginal colonization or infection which cause vaginal colonization or infection (especially shedding material, high absorbency and chemically bleached tampons can cause the toxic shock syndrome, since particularly short, straight sharp fibres damage the vaginal walls and absorb the protective vaginal microflora).
  • Toxic shock syndrome can progress rapidly. Complications may include shock, renal failure and death.
  • sea sponges are used to absorb the menstrual fluids. They are pleasant in structure, soft, and 100% natural. However, their use is not convenient due to complicated insertion/removal, a form that is not adapted to the environment that it's used in, and the need to wash it well after each use (reusable material). Also, the absorbed liquid may leak. They are particularly expensive to use as a single-use device. Because the sea sponge is a naturally occurring product, it is non-sterile and has various impurities. The US Food and Drug Administration (FDA) treats them as exceptionally risky devices that do not have the FDA approval as menstrual tampons. Data from the FDA studies shows that sand and gravel particles, bacteria, yeast, soil and even Staphylococcus aureus bacteria have been found in sea sponges.
  • the closest analogue is disclosed in European patent No. EP2448536 .
  • the described compressed menstrual tampon comprises an elongated rod-shaped body with a filler having an insertion end and a withdrawal end having a withdrawal string.
  • the absorbent body with the filler expands as the fluids are absorbed and can be made from viscose, cotton, or cellulose pulp.
  • the absorbent body with the filler may also comprise or consist of an absorbent sponge.
  • the tampon also includes means to ease the insertion, such as an applicator that conforms to the tampon shape, from which the tampon can be expelled.
  • this type of menstrual tampon is rigid, absorbs excessive amounts of moisture from the vaginal walls, is made up of small and sharp fibres that damage the vaginal walls and natural microflora, leaving small cotton fibres with old blood particles in the vagina, it can also disturb the vaginal pH and cause infections, the fluids can leak, or may cause discomfort due to uncomfortable shape.
  • DE 28 40 340 A1 discloses a menstrual tampon having a cellulose sponge as an absorbent body.
  • US 2015/0209468 A1 discloses a feminine sanitary napkin comprising a fibrous absorbent element and a prebiotic made of glucomannan. Further prior art related to feminine hygiene articles can be found in US 2002/0412693 A , WO 2012/150546 A1 , WO 2010/055115 A1 and US 4,553,965 A .
  • the object of the present invention is to provide a menstrual tampon which does not have at least the aforementioned disadvantages, i.e.
  • menstrual tampon which does not harm and does not irritate the vaginal walls, does not damage the mucous membrane, reduces the likelihood of infection, facilitates insertion, prevents excessive absorption of bodily fluids, prevents leakage of menstrual fluids, is convenient during use.
  • tampons that are commonly made from absorbent fibres
  • our menstrual tampon accumulates fluid in its pores due to the sponge structure.
  • the menstrual tampon of the invention is intended to be introduced into the vagina to absorb menstrual fluids.
  • the tampon comprises a premoistened material of natural origin for absorption of menstrual fluids having a uniform porous sponge structure whose molecular structure prevents the occurrence of small fibres and is gentle to the vaginal walls, elastic, and shaped for an easy vaginal insertion.
  • the special shape of the tampon and its porous structure facilitates the adaptation to the vaginal walls and ensures the impermeability of the fluids.
  • the liquid is absorbed where it is formed and safely retained inside the tampon. Since menstrual blood flows into and is retained in the pores of the sponge, the absorption pattern is fundamentally different from the conventional tampons that perform the function when the blood is absorbed by the tampon fabric itself. Menstrual blood accumulated in the pores of sponges is isolated from the vaginal walls, thus maintaining a healthier vaginal pH, where the healthy vaginal pH is more acidic (equal or less than 4.5) than the blood pH (about 7), thus preserving healthy microflora of vagina and reducing risk caused by pathogenic bacteria.
  • the sponge structure allows the tampon to be compressed and deformed during use, ensuring convenience, but also function.
  • the tampon When the tampon is inserted, the sponge recovers its shape particularly fast due to the sponge structure, the material from which it is made of and its porosity. Softness, flexibility and special shape make it easy to adapt to individual physiology without causing discomfort.
  • the tampon also may have an outer fluid-impervious layer that provides fluid retention in the tampon even when its deformed during use, i.e. prevents leakage of fluid as the person moves causing squeezing, bending and similar deformation of the tampon material.
  • the tampon also may include an applicator for easy insertion and a cord or ring for convenient removal, but it can also be used without an applicator.
  • An exemplary embodiment of a menstrual tampon (1) includes an absorbent tampon body (2) comprising a solid absorbent material like a sponge structure material, such as a plant-derived material that can easily deform and readily reform to a non-deformed, or partially deformed state, at least in the humidified state.
  • a solid absorbent material like a sponge structure material
  • Such material can be produced from Amorphophallus konjac (Konjac plant) plant root powder by production of glucomannan and subsequently processing it by a specific method in order to obtain the sponge structure, or it can be made from other naturally occurring polysaccharides, such as starch, cellulose, chitin, and their mixtures, without limitation.
  • the said glucomannan is a substance used in food industry, also in medicine for wound dressing which, together with lactobacteria, inhibits the growth of bacteria such as Staphylococcus aureus which cause the Toxic Shock Syndrome and S. typhimurium.
  • the product contains no toxic chemicals and the resulting final product is chemically pure and biocompatible with the human body i.e. ensures protection of natural vaginal microflora and healthy intimate hygiene. Due to its biological origin, glucomannan-based sponge and all its additives are biodegradable and decompose naturally in nature.
  • Glucomannan is hydrophilic and, thanks to its unique molecular structure, attracts water molecules, so the tampon walls are always moist and come in contact with the vaginal walls with a molecular barrier of liquid - protecting extremely sensitive vaginal walls.
  • the tampon (1) also includes a liquid impermeable layer (3) which at least partially retains the moisture in the tampon (1) until its use and prevents the leakage of liquid from the tampon during its use.
  • the said layer (3) covers more than half, half, less than half or none of the outer surface of the tampon (1).
  • the tampon (1) may also comprise an outer reinforcing casing (not shown in the drawing), which reinforces the structure of the tampon (1) and helps maintain the desired shape.
  • the tampon (1) comprises a removal facilitator (5), such as a thread or string.
  • the aforementioned removal facilitator is attached at two ends to the tampon approximately in the central region or the upper part (6), or the lower part (7), on opposite sides of the tampon so as to form a U-shaped loop that extends from one edge of the tampon to the other, and forms the possibility of a gap between at least the lower part (7) of the tampon (1) and the means for facilitating removal (5).
  • the removal facilitator (5) can also be formed as a single element that is pierced through the body (2) of the tampon (1) at any location, such as the upper, central or lower body (2) of the tampon.
  • the tampon (1) may be irregular in shape, similar to an oval, or any other sleek shape.
  • the upper part is wider than the lower part, or of similar diameter.
  • the width (10) of the tampon (1) is larger than the thickness (12) in order to reproduce the natural biological vaginal canal form (https://i.pinimg.com/originals/d9/d1/3b/d9d13b90a7d2c5ba6e5314f2c8b3258f.jpg) to create a comfortable experience for the user.
  • the upper part (6) which is designed to absorb the menstrual fluids is wider than the lower part (7), which is designed to retain the accumulated fluids.
  • the top portion (6) of the tampon (1) may also include a hollow (8) comprising a concave inner tampon surface (9) formed to have a maximum fluid absorbing surface that is not coated with fluid-impervious layer.
  • said layer (3) may cover the entire outer surface of the tampon (1) up to the edge of said hollow (8). In other embodiments of the invention, said layer (3) may wrap a tampon (1) at a distance to the edges of the hollow (8), so that the outer portion of the tampon body (2) remains uncoated to the edges of the hollow (8).
  • the hollow (8) is designed for cervix and easier fluid accumulation, and for faster fluid uptake to prevent blood stagnation at the cervix.
  • the hollow surface comprises a portion of the material of the tampon body (2) and can be curved and/or concave in shape, such as a scoop, hollow half-sphere, oval, or any other form, such as comprising the convex and concave forms.
  • the edges of the hollow (8) may be concave (11) at the lateral portions of the tampon (1) and convex (11') at the top and centre of the tampon.
  • the hollow (8) may be in the upper portion (6) of the tampon, the top of the tampon, the scoop, the hollow half-sphere, the oval or any other and irregular shape ( Fig. 3 ).
  • the tampon (1) comprises at least a non-deformed state when it is fully expanded, deformed state, when it is compressed to occupy the smallest possible volume, and a partially deformed state, during which the tampon fills the entire cavity by partially deforming the cavity walls at the contact site.
  • a partially deformed state during which the tampon fills the entire cavity by partially deforming the cavity walls at the contact site.
  • Reversible deformations of the tampon body (2) ensure that the adaptation to the vagina will take place continuously, while the user is both at rest and during movement.
  • the deformed tampon body (2) recovers its original or partially original shape.
  • the material of the tampon (1) body (2) is impregnated with water and/or other materials of liquid form.
  • the impregnant moisturizes the entire material of the tampon body (2) so that it switches from the natural solid state to a soft state.
  • Such impregnated sponge-based tampon (1) does not dry the mucosa, but at the same time absorbs excess moisture, facilitates the insertion and removal of the sponge without damaging the particularly thin vaginal skin, since it has a soft and mild structure.
  • a variety of substances which have a positive effect on vaginal microflora can be used as an impregnant including various medications and plant extracts to relieve and/or reduce menstrual pain or for other purposes.
  • Impregnation of sponge material with medication is a safer way to treat diseases than an oral drug intake because it protects the liver and digestive system. Due to the thin vaginal mucosa, drugs are able to reach target areas much easier. And the material from which the sponge is made improves the release and absorption of the drug.
  • Impregnants can perform an additional therapeutic or preventive function such as:
  • This invention also comprises a waterproof package for said tampon (1) which retains sterility and the moisture of the body (2) of the tampon (1).
